I am looking for information regading the 7Z and 8A modifiers when billing the following CPT codes for Cystic Fibrosis lab tests:
83891 83900 83901 83909 83912 83914 Can someone explain to me if these modifiers are appropriate and at what times they would be used with these codes. I never come across this and have searched the internet looking for something without much luck. Thank you in advance for any assistance! Last edited by pherja; 02-02-2009 at 02:31 PM. |
